A kidney biopsy is a procedure in which a small sample of kidney tissue is taken and examined under a microscope. It helps doctors diagnose kidney problems, monitor disease progression, and guide treatment. The test is usually recommended when blood or urine tests show abnormal results, or when kidney function is worsening without a clear cause.
A kidney biopsy (renal biopsy) involves removing a small piece of kidney tissue using a special needle. The tissue is then analyzed to check for signs of inflammation, scarring, infection, or other diseases.
A doctor may recommend a kidney biopsy to:
The procedure is not painful because local anesthesia is used. Some patients may feel slight pressure during the biopsy. Mild soreness in the back or biopsy site may occur afterward, which usually improves within a few days.
Kidney biopsy is generally safe, but potential risks include:
Most patients go home the same day or the next morning. Full recovery is usually within 2–3 days, though activity restrictions are advised for a week.
